MODE OF INCREASING ADHESION OF DRIVING-WHEELS 0F LOCOMOTIVES.

Specification of Letters Patent No. 2,228, dated August 28, 1841.

To all whom it may conce/m:

Be it known that I, JORDAN L. Mor'r, of the city of New York, in theState of New York, have invented a new and useful method or apparatusfor the purpose of producing adhesion between the wheels of locomotivesteam-engines and the rails of railway-tracks, by which device suchengines will be enabled to overcome the slipping of the wheels,consequent upon oil, ice, &c., upon ascending grades without its beingnecessary to throw any additional weight upon the wheels for thatpurpose; and I do hereby declare that the following` is a full and exactdescription thereof.

My improvement consists in the combined application of moisture and ofsand or other grit, to the wheels, by means of which the sand may bedistributed over the surface of the tire, or tread, of the wheel, andwill be made to adhere with suiiicient force and in suflicient quantityto produce the required adhesion.

In the accompanying drawings, Figure 1, is a perspective representationof a locomotive steam engine and carriage, having two driving, and fourtruck, wheels, to the former of which my apparatus is applied; itsapplication, however, is not limited to locomotives of any particularconstruction, but is equally adapted to those with foursix, or eight,driving wheels. Fig. 2, is an end view, and Fig. 3, a side view of suchpart of a locomotive as is requisite to show the manner of applying myapparatus.

A, is the steam chamber, and B, the body of the boiler, which may beconstructed in any of the ordinary forms.

O, O, are hoppers, or boxes, for containing sand; the lower portions S,of which boxes are to be charged with this material in a dry state.These hoppers may be varied in situation, but I, in general, place themdirectly over the centers of the driving wheels; the sand is to bedischarged from them through a tube, or opening, at their lower ends,which opening is governed by a valve, or sliding shutter, by which itcan be properly regulated.

a, represents the handle of such a valve, or sliding shutter, which maybe constructed and managed in any of the known ways of constructing andmanaging devices of this kind.

D, D, are steam, or Water, pipes which are to convey the moisture to thewheel from the steam chamber, boiler, or other source; these pipes areto be governed by a stop cock, as shown at c, 0,' and they discharge thewater, or steam, on the periphery of the wheel, and moisten it, directlyin advance of the aperture for the discharge of sand; if steam is used,it will be condensed upon the wheel, but it will, probably, be found toeconomize heat by using water; the quantity expended in either case willnot, however, be important in amount. Instead of using the water, orsteam, from the boiler, water may be conducted through the pipes from acistern, or reservoir, of cold water, placed in any convenient situationfor that purpose. Although I prefer to discharge the sand and moistureupon the wheels, it will be manifest that they may be directed with likeeffect on to the rails in advance of the driving wheels, and that thecombined operation of the moisture and sand will be the same; but theapparatus will, in this case, have to be extended, without producing acorresponding advantage. Such an arrangement is shown with a hopper atS', with steam or water pipes at D, and a, o, tubes for the discharge ofsand.

Having thus, fully described the nature of my invention, and shown howthe same may be carried into operation, what I claim as new, and desireto secure by Letters Patent is l. The applying of sand to theperipheries of the driving wheels of locomotive engines, in combinationwith the application of water, or steam, to moisten the wheels for thepurpose of causing the sand to adhere thereto, substantially in themanner set forth, and so as to enable such locomotives to ascendinclined planes, or elevations, on a railroad, in consequence of thefriction produced by such application.

2. I claim, also, the applying of moisture and sand simultaneously tothe tops of the rails in advance of the driving wheels, by means of theapparatus herein described, considering this mode of applying themoisture and sand as a mere modification of the general principle uponwhich the utility of my invention is dependent.
